Intel Core i7-5960X 8-Core Haswell-E Processor Review

Euler3d CFD Benchmark

Next up is the STARS Euler3d CFD benchmark. The benchmark is intended to provide information about the relative speed of different processor, operating system, and compiler combinations for a multi-threaded, floating point, computationally intensive CFD code. The benchmark testcase is the AGARD 445.6 aeroelastic test wing. The wing uses a NACA 65A004 airfoil section and has a panel aspect ratio of 1.65, a taper ratio of 0.66, and a 45 degree quarter-chord sweep angle. This AGARD wing was tested at the NASA Langley Research Center in the 16-foot Transonic Dynamics Tunnel and is a standard aeroelastic test case used for validation of unsteady, compressible CFD codes.

The benchmark CFD grid contains 1.23 million tetrahedral elements and 223 thousand nodes. The benchmark executable advances the Mach 0.50 AGARD flow solution. The Intel Fortran compiler (ifort 10.0) is used and all floating point variables are Fortran’s double precision (8 bytes). Parallelization is through OpenMP. The benchmark score is reported as a CFD cycle frequency in Hertz and that is what we used to make out chart.

Benchmark Results: The clock speeds of the Core i7-5960X don’t make for impressive scores when using fewer than 8 threads, but once you get to 8 or more threads the performance is untouchable! Our score of 12.144Hz on the 16 threaded test is higher than we have ever seen before.

  • Price of DDR4 is bad I bought 32 GB will wait on the other half .

  • I ordered a i7 5930k for my Haswell-E Build, hopefully it arrives by this weekend but for me I just cant justify the cost of the 5960X. 2011-V3 socket will have plenty of new chips coming out during its life span so I expect to see 8-core chips fall to the $400 range in the next year or two. I’m happy with my 2500k but just have the itch to upgrade and would like to to run crossfire 290s now that they can be had for $250 and my current motherboard is PCI-E 2.0 and will run then 8x 8x, plus I could use the extra encoding speed of the new Haswell-E chip. Anyways I’m excited!! great review as always!

      Sorry pal, I’m from the future and I have to tell you, your assumption is wrong. Looking at the price of the i7 6900k Octa-Core makes me laugh when I read your comment. Its about 1,100$ right now. I don’t think Octa-Cores will drop below anywhere near 400$ or 500$ within the next 5-6 years.

    Do you know if PSU Corsair AX850 can handle 5960X at 4.4-4.6Ghz?

    • yeah, it sure can

    • A friend had one overclocked at 4.4GHz with a 780ti overclocked to I think 1120mhz, and he was drawing about 550 watts at full load.

    Next year Q4 the regular Chips will be out and run DDR4 on new M.B, by then the Ram should come down in Price. No time date only rumor that a 3.5 6 core for 350$ will be the high end. I’ll wait.

    You’ve got remnants from G3258 pages in the Overclocking section and likely elsewhere, but that’s the only page I read.
